14-10-20037y710-Air: J.E.M.H. van Bronswijk1 Health risks from the air Opportunities & Problems
14-10-20037y710-Air: J.E.M.H. van Bronswijk2 Air is Life Death occurs after a few minutes without oxygen
14-10-20037y710-Air: J.E.M.H. van Bronswijk3 Indoor Air Perishable Commodity (< 24 Hours) Remove and replenish constantly Intelligent Control ( Smart Buildings / Domotics / Ambient Intelligence ) Bio-film development on Surfaces ( commonly also inhabited by mites and insects ) Beware of Biowar!
14-10-20037y710-Air: J.E.M.H. van Bronswijk4 CO 2 as a pollution marker Pollutants in the Indoor Air Pollutants in the Indoor Air 340 ppm Outdoor value 340 ppm Outdoor value 700 ppm Airway irritation in Chronic Lung Patients 700 ppm Airway irritation in Chronic Lung Patients 1000 ppm Airway irritation in most persons 1200 ppm Hygienic limit in Netherlands Schools

14-10-20037y710-Air: J.E.M.H. van Bronswijk12 The 6 Global Risk Areas for mite growth and survival in carpeting of well ventilated and heated rooms 1. No survival 2. Survival on poorly insulated ground floors 3. Survival on all floors 4. Growth on poorly insulated ground floors 5. Growth on most floors 6. Growth on all floors 1. 2. 3. 4. 5. 6.
14-10-20037y710-Air: J.E.M.H. van Bronswijk14 Healthy and Sustainable Building Healthy Indoor Air Disease Risks: - Asthma & other allergic disease - COPD (Chronic Obstructive Pulmonary Disease) - Lung Cancer - Veteran’s Disease / SARS (aerosols) Prevention: - Keep CO 2 -concentration below 700 ppm - Harmonize pollutant production with ventilation intensity - Keep RH below 55% for at least 3 consecutive months/year - Use emission-low finishing materials - Prevent aerosol-formation and beware of fibres floating in the air
14-10-20037y710-Air: J.E.M.H. van Bronswijk17 Safety Plan - Safety analysis of potable water supply, air exchange, and sewage disposal - Attack safety leaks (Design & Maintenance) - Fast Biosensors with 24-Hour monitoring - Double Systems
14-10-20037y710-Air: J.E.M.H. van Bronswijk18 Anti-Bioterrorism Activities (near Future) - Design for safety - Security analysis of design - ‘Embedded’ safety systems - Biosensor-update Subscription Biochip with built-in telemetric facilities http://ws351.uncc.edu/tpw/bio/bchip.htm
